TEXAS INSTRUMENTS · Global Sourcing Parts · SOT-23-5

TL391LVDBVR from TEXAS INSTRUMENTS, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Open-collector comparator output that needs an external pull-up; absolute maximum voltage from GND is -0.3 V to 6 V and the output short-circuit duration is limited to 10 s.
2 GND power_in Ground pin serving as the negative supply (V-) reference; split supplies are supported with V- applied to this pin.
3 IN- input Negative (inverting) comparator input; input voltage range is -0.1 V to 5.6 V from GND and input current is limited to ±10 mA.
4 IN+ input Positive (non-inverting) comparator input; input voltage range is -0.1 V to 5.6 V from GND and input current is limited to ±10 mA.
5 VCC power_in Positive power supply; the recommended supply range is 1.65 V to 5.5 V, with an absolute maximum of 6 V.
